The electric conductivity of ZnF2-AlF3-PbF2-LiF glasses has been studied in the frequency range 10 Hz-2 MHz and in the temperature range from 300 K to just below the glass transition temperature. The conductivity decreases with the increase in the LiF content in the composition, which results from the trapping of F- ions by Li+ ions. Small values of the stretching exponent β are observed for the present glasses. The value of the decoupling index decreases with an increase in LiF content, consistent with the composition dependence of the conductivity.
